Are replacement trucks actually available for Spectrum passenger cars as seen when googling Bachmann diecast ho passenger trucks as seen in pic #1 of Images. Pic shown has correct truck and power connection wire. When clicked on you are sent to shop bachmann com page with only freight trucks at the bottom of the page.How else could they be listed if still available?What about replacement isolated wheel sets for same? My used cars are really USED and one end of the axles are blunted and one side of the truck is worn oval as the cars must have only gone in a circle one way for years!
